netfilter: bridge: fix IPv6 packets not being bridged with CONFIG_IPV6=n
230ac490f7fba introduced a dependency to CONFIG_IPV6 which breaks bridging
of IPv6 packets on a bridge with CONFIG_IPV6=n.
Sysctl entry /proc/sys/net/bridge/bridge-nf-call-ip6tables defaults to 1,
for this reason packets are handled by br_nf_pre_routing_ipv6(). When compiled
with CONFIG_IPV6=n this function returns NF_DROP but should return NF_ACCEPT
to let packets through.
Change CONFIG_IPV6=n br_nf_pre_routing_ipv6() return value to NF_ACCEPT.
Tested with a simple bridge with two interfaces and IPv6 packets trying
to pass from host on left side to host on right side of the bridge.
Fixes: 230ac490f7fba ("netfilter: bridge: split ipv6 code into separated file")
